Processing Nozzle with Slide Mechanism for Dynamic Spot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing nozzles require nozzle exchange when changing shaping conditions from fine writing to bold writing, leading to inefficient material usage due to a fixed spot position of the processing material, which does not have an appropriate relationship with the laser beam's condensing region.
Innovation Solution
A processing nozzle design featuring a cylindrical inner and outer housing with a slide mechanism that adjusts the relative position along the energy line, changing the size of the ejection port for the processing material, allowing for dynamic adjustment of the spot diameter without needing nozzle exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed spot position nozzle is used, then the structure is simple, but the adaptability to different shaping conditions deteriorates
Solution Approach 1:
The nozzle incorporates a slide mechanism that enables dynamic adjustment of the outer housing's position relative to the inner housing, allowing the ejection port size to be changed along the energy line direction. This dynamic structure allows a single nozzle to adapt to different shaping conditions (fine writing to bold writing) without requiring multiple fixed nozzles, thus improving adaptability while maintaining reasonable structural complexity
Solution Approach 2:
The invention changes the physical parameter of the ejection port size by adjusting the relative position between the inner and outer housings. By sliding the outer housing along the energy line, the gap size (ejection port) is varied, which directly changes the spot diameter of the processing material. This parameter change enables the same nozzle to serve multiple shaping conditions
2Manufacturing precision
If multiple nozzles are prepared for different writing modes, then the shaping precision is maintained, but the device complexity and operation time increase
Solution Approach 1:
The nozzle is designed with multi-functionality to perform both fine writing and bold writing tasks using a single device. The slide mechanism allows the same nozzle to adjust its ejection port size to match different laser beam condensing regions, eliminating the need to exchange nozzles when switching between fine and bold writing modes, thus reducing operational time while maintaining shaping precision
Solution Approach 2:
The dynamic adjustment capability allows rapid switching between different ejection port sizes without the time-consuming process of nozzle exchange. The slide mechanism can be quickly adjusted to change the gap size, enabling fast transition between fine and bold writing modes while maintaining the precision required for each mode
3Adaptability or versatility
If the ejection port size is fixed, then the manufacturing precision is high, but the adaptability to different spot diameters deteriorates
Solution Approach 1:
The ejection port size is made dynamic through the slide mechanism, allowing continuous or stepped adjustment of the gap between the inner and outer housings. This enables the nozzle to adapt to different spot diameter requirements while maintaining precise control over the ejection port dimensions, as the slide mechanism can be positioned at specific intervals or continuously adjusted to match the required spot size

AI summary
A machining apparatus that need not exchange a processing nozzle when changing a shaping condition, and increases the use efficiency of a material. The processing nozzle that performs processing by ejecting a processing material towards a molten pool formed on a process surface by an energy line includes a cylindrical inner housing that incorporates a path through which the energy line passes, and ejects the energy line from one end. The processing nozzle also includes a cylindrical outer housing that incorporates the inner housing, and has an inner surface tapered in the ejection direction of the energy line ejected from the inner housing. The processing nozzle also includes a slide mechanism that changes, along the energy line, the relative position of the outer housing with respect to the inner housing.
